The Washington Redskins knew after Sunday's loss to the Dallas Cowboys that the news was bad about the knee injury suffered by running back Ladell Betts.

This morning it's been revealed that the news is really, really bad.

Adam Schefter of ESPN reports that Betts has a torn ACL and MCL and will need surgery.

That type of injury doesn't just put him out for the season; it also calls into question whether he'll be ready for next season -- especially with a running back who's on the wrong side of 30.

Betts was starting in place of the injured Clinton Portis, who is expected to miss at least one more game. Rock Cartwright and Quinton Ganther carried the load for the Redskins after Betts went down, and the team may need to sign a running back this week.
